[erlang-questions] binary_to_integer/1 and binary_to_float/1 and friends

[Richard Carlsson]

EEPs should only be needed for changes to the language itself, or more 
far reaching changes to the standard libraries. For a small change like 
this, just submit it as a patch and see if OTP will take it in. Don't 
forget that documentation and test cases are needed as well.
